The images in the series “On the Road: The Catholic Church in China 1992-1996” are grimmer. The PRC banned religion in the early 1950s, forcing people to worship underground. During the Cultural Revolution, the Red Army raided the homes of Catholics and confiscated Bibles and religious objects. In one of Lu’s images, an elderly woman, a fifth-generation Catholic, clutches a large crucifix hidden by her husband during the Cultural Revolution. In another, Lu captures the spartan, dirt-floored room of a 70-year-old lay nun. It’s a portrait of her with her adopted daughter, a frail, abandoned casualty of China’s one-child policy. Anyone who has or adopts the second child of a family with one child can be fined. The nun was forced to hide the child from the authorities, who have tried to investigate.
